SPECIFICATION forming art of Letters Patent No. 435,361, dated August 26, 1890.

Application filed June 6, 1890. Serial No. 354,486. (No model.)

To all whom it may concern:

Be it known that 1, JOHN KIRBY, J r., of Dayton, county of Montgomery, and State of Ohio, have invented certain new and useful Im-, proveinents in Oar-Lamps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to hanging-lamps for railway-cars, boats, and similar uses, and is adaptable to the Bombay and ordinary hanging patterns of such lamps, the drawings representing the Bombay pattern. It is constructed on thewell-known tubular principle of supplying air to the burner, and requires no chimney within the globe.

One'purpose of my invention isto produce a lamp on the tubular or hurricane principle which of itself is complete and independent of the exterior ventilator or hood, so that its successful operation is dependent upon the manufacturer and not to any material extent upon the particular construction or thickness of the roof, or upon the skill of the person putting the lamp into position for use in the car.

Another purpose is to provide combined means for admitting air to the burner and detachably securing the globe in position in such manner as to prevent the admission of air between the upper and lower ends of the globe and its holders by the jostling motion of the car, as air so admitted frequently extinguishes the flame or causes it to smoke.

A further purpose is to provide convenient means for readily operating the top globeholder. Y

A further purpose is to provide the lamparms with adjustable means for securing the lamp in position to the car-roof, whereby it is adaptable to varying sizes of well-holes, by the necessity for making the lamp and well-hole in which it is to be placed to exactly fit each other is avoided, which is a great convenience to both the lamp-manufacturer and the car-builder, and which feature ofmy invention is not of necessity confined to lamps of the particular type described herein. To these ends, my invention consists in certain improved arrangement of parts, as

4 appurtenances,

hereinafter fully described and as .shown in the accompanying drawings, in which-- Figure 1 is a side view of the lamp and its showing the well-hole and a portion of the car-roof, one-half being shown in full and one-half in cross-section through its center. Fig. 2 is a perspective view. of the lamp proper detached from the car-roof. Fig. 3 is a perspective view of the oil reservoir and burner detached from the body-ring. Fig. 4; is a perspective view of the body-ring and lower globe-holder. Fig. 5 is a perspective view of the upper globe-holder; and Fig. 6 is an inverted plain view of the top globeholder and band-ring surrounding it.

Like letters of reference indicate corresponding parts in the several figures.

Arepresents a frame,usually termed wellhole, and ordinarily made circular in form, with a return or flange B, to receive the reflector O. This frame is made to fit an opening out through the roof D, to admit the reflector and lamp. The well-hole is covered by a hood E, provided at its center with an ordinary ventilator F, for the escape of the products of combustion. G is a ring forming the lamp-body, to which the reservoir H couples by means shown and described in United States Letters Patent No. 93,602. Other forms of couplings may, however, be employed. The ring G maybe of any suitable form,with an opening in its center into which the burnercone J snugly fits, as shown at a, Fig. 1, to prevent the airforsupplying theburnerfrompassing around the outside of the burner-cone into the globe, and for directing the said air through a series of small openings 1) c to the flame in the usual manner.

A globe-holder K is carried by the bodyring G and supports the lower end of the globe L. This holder is provided with a series of small openings 6, to admit a required amount of fresh air to within the globe to form perfect combustion under all conditions of the surrounding atmosphere.

M is the top globe-holder, preferably made of thin sheet metal, provided with a series of openings f and a deflector N, extending inwardly and downwardly from its outer walls, with an opening g in its center. The said globe-holder is also provided with a thumbpiece 0, extending through the center-of and below the deflector N, and a screw-threaded neck P, to engage with a corresponding screwthreaded neck Q, extending from a band or ring R surrounding the said globe-holder, which band or ring is provided with openings to admit air to tubes S, any suitable number of which may be employed to conduct the air to the burner. The openings in the globeholders and band or ring and the arrangements of parts adjacent thereto are such as to allow the proper circulation of air from within and without the globe to cause the flame to burn steadily and without smoking under all conditions of the surrounding atmosphere. i

The tubes S are secured at theirlower ends to the ring G and at their upperends to the band or ring R, and thus form a complete and rigid frame for the lamp proper, distinct from and independent of the exterior hood and ventilator. Arms T are secured to the tubes S and extend outwardly, their outer ends being provided with screw-threads and corresponding screw-threaded sleeves U adapted to lengthen or shorten the arms T, thus adapting the lamp to well-holes of various diameters, to the walls of which the sleeves are screwed by means of projecting ears h, as shown in Fig. 2. Other means of adjustment for the sleeves may be employed, but I consider the screw-threads preferable.

The operation of my improved lamp is as follows: The wick is adjusted by turning the button 2', which is connected to a shaft Z, extending through a tube m within the oil-reservoir. To the opposite end of this shaft is secured a cog-wheel n, which engages a corresponding cog-wheelp, connected to the end of the ordinary wick-raising shaft. Thus, when the cog-wheel n is turned, the wick-raising shaft is also made to turn, and the wick is thereby adjusted from below the lamp without the necessity of removing the oil-reservoir. To remove a globe the oil-reservoir is first removed and the arm inserted through the globe, when, by turning thumb-piece O, globe-holder M is unscrewed sufificiently to allow the globe by slightly raising and tipping to be removed. When replaced, the globe-holder M is screwed down until its lower rim rests solidly on the bead V. Air for supplying the flame is taken from a point near the top of the globe and from within the space formed by the upper globe-holder M and band or ring R, down tubes S, through space W, to the burner, as indicated by arrows. The heated airand other products of combustion pass 01f partially through the center opening and partially through openings f of the top globe-holder, thus mixing with and warming the air supplied to the flame before finally escaping through the ventilator F.

Having thus fully described my improved lamp, I claim as my invention- 1. In a car-lamp, a body-ring carrying a globe-holder, an oil reservoir and burner detachably connected with said body-ring, a globe, and a top globe-holder adj nstably supported and carried by a band or ring surrounding the same, in combination with tubes connecting the said band or ring with the bodyring, the said tubes forming conduits for the passage of air to the burner and being provided with means for and the whole structure adapted to attachment to a car-roof from beneath the same.
